An unknown tool i found.

[Barry]

Hi there,


This unusual tool was lying in my grandfathers attic, between old parts of jaguar cars. It has been untouched for years, and neither of us have any idea what it is or what it does. I'm hoping people here can help.

Thanks in advance!

a couple of more pics may help????
there is a -2 stamped in it, that somewhat unique to British cars setting up ring and pinion gears. The brass ball / counterweight???  grease caps 2 on end of a pivot???   interesting to say the least!

goodfellow over at the GG restores old Jags; he'd likely know if that's Jag-related...

He seems to be registered here, but has never posted. I'll let him know his expertise is needed.

Sorry guys -- I have no idea what that tool does.

Looks a little like some sort of gemstone facetting tool - assuming that the angles can be adjusted as well as the depth...  Bottom left shows two oilers, indicating a need for lubrication, so I assume some sort of revolving cutter could be fitted to the spindle....

However, most gemstone tools run on a flat copper disc, used with abrasive powder, so maybe some form of tool and cutter grinding jig....

Looks like some precision tool holder, with angle marks & various adjustments to set a tool (dial indicator) position...

I have an overload of lapidary tools -I don't think this is one ( no index, no way to move around the shaft, etc.) I considered a dop transfer jig, based on the gem lap idea, but I cant see how.  I think the best lapidary jig is a cabochon jig - a dop with a stone mounted at a right angle on the end ofvthe swivel arm.  The whole thing mounted to the front of the grinder.  The depth of the center pin would set the dome across the top ov the cab. Then I realized lapidaries aren't that fancy and the slurry would ruin the precision that it looks like this tool has.

First thought was the most complicated graver jig, but again no way to move the assembly over a sharpening stone...

Then I thought perhaps it is some kind of gouge sharpening jig, mounting the gouge in the left end pointing down.  Mounted to the front of a grinder you could move a gouge back and forth, pivoting around the centerline set by the center screw. This is just my best swag.

I'll tell you what, it is one of the most adjustable jigs I have seen, if it is a jig.

If it is for a jag it is probably for setting the eindow washer sprayer outlet angle (j/k - mostly brain dead)
